Abstract
Abstract A fire resistant polymer composition comprising 99.9 to 50 parts by weight of a copolymer consisting essentially of 90 to 10 weight percent nuclear-halogenated aromatic vinyl compound, 10 to 90 weight percent cyanized vinyl compound, and 0 to 30 weight percent one or more monomers copolymerizable therewith; 0 to 20 parts by weight rubber-like polymer; and 0.1 to 30 parts by weight of a member selected from the group consisting of iron family compounds, tin compounds, and mixtures thereof.
